Network configuration with SIMATIC Manager
The SIMATIC Manager Step7 is the network configuration tool that will be used to configure
the PROFIBUS DP network.
SIMATIC Manager uses GSD files in order to know the properties of the devices in the
network configuration. The configuration is then loaded to the PLC for informing the PLC
about the PROFIBUS slaves in the network.
After the network configuration is loaded to the PLC, the PROFIBUS communication will be
started by the PLC with the configured slaves.
The steps for creating and loading a Step7 project are:
1.
Create the project by selecting CPU and organization blocks.
To do so use the 'New Project Wizard'.
2.
Build the network configuration in hardware configuration window and compile.
3.
Write the application software for the organization blocks in STL, LAD or FBD.
4.
Adjust the PG/PC interface.
5.
Download hardware configuration, system data and the organization blocks to the PLC
6.
Wait for the PLC to restart.
7.
Check the status LEDs on the PLC for a proper PROFIBUS communication. The Red SF
and BF LEDs must be off and the green RUN LED must be on.
